Yes, but I talk the reference implementation (DMD) here.

GDC has various other problems:
  - The latest binary release is 2.058
  - Phobos and druntime are not trivially recompileable without 
compiling the whole thing beforehand
  - Couldn't find clear compiliation setup documents.
  - Phobos and druntime have a completely different folder structure 
(for whatever reason)

Also the thread local storage issue is a druntime issue AFAIK and exists 
within gdc as well.
